What is the theoretical probability of randomly selecting a 3 child family with 3 girls?
The gender of children is not a constant. It depends on the parental predispositions - mainly on the father's genes but apparently the mother's age can also affect the gender. The details of these influences are not understood well enough to develop an accurate model.
If you make the simplistic but unjustified assumption that both genders are equally likely, the answer is 1/8.

What is the probability of randomly selecting a three-children family with exactly two girs?
It is 3/8.

Theoretical probability that a family of 4 children will be all girls?
4/6=2/4 n(s)=3 6
What is the probability of randomly selecting a three-child family with exactly two girl children?
2/6 is not accurate. using a theoretical method for equally likely outcomes, there are 2 possible outcomes for each birth: either a boy(B), or a girl (G). For a family of three children, the total number of possibilities (birth orders) is 2*2*2=8 to double check this work, here are the eight possible outcomes:BBB, BBG, BGG, GBB, GBG, GGB, and GGG. You want EXACTLY two girls, this assumes that the other must be a boy. Therefore, the probability that a three child family has 2 girls one boy is P(2 girls)=3/8=0.375
What is the probability of 4 boys in a family with 4 children?
In a family with four children, the probability of having four boys is 1 in 16.

If a family has had 3 boys in a row what is the theoretical probability that the next child will be a girl?
The probability of having a boy or a girl is always 50/50 each time, regardless of previous outcomes. So the theoretical probability of having a girl after having three boys in a row is still 50%.
What is the probability of having a family of ten?
If the family consists of a pair of parents and their offspring, then the probability is very close to 0.
What is the probability of 4 boys in a family with 4 children?
In a family with four children, the probability of having four boys is 1 in 16.
What is the probability that the 6 child family has exactly two girls?
The probability is 2 - 6
What is the probability of a family having a boy after four girls?
The probability of a boy is still 0.5 no matter how many prior children there are.
What is the probability of getting 3 girls in a family of 10 children?
The probability of exactly 3 girls in a family of 10 children, assuming equal chance of a boy or girl, is 0.1172. This is a binomial distribution.
In a family of 5 what is the probability that you will have 3 girls (please show your work)?
The probability of a female is approx 0.4831 across the world. If you assume (rather dubious) that the genders of children in a family are independent then the probability is approx 0.3012In a family of 5, the probability of 3 girls and 2 boys is5C3*(0.4831)3*(0.5169)2 = 0.3012

By showing the history of genetics in the family
